Each post/article in the portal is tagged using one or more vocabulary terms defined in my modeling taxonomy. Clicking on the term will retrieve a view page listing all drupal nodes (i.e. posts+articles) tagged with the same term.
Until now, clicking on the term redirected the user to an error page but now I've managed TO fix the problem (AT least temporarily, it seems it IS NOT clear yet what makes Drupal TO generate wrong aliases FOR the terminology terms).
Hope you enjoy a new way OF browsing the site
